Some techniques used in this type of radiotherapy comprise:
IGRT is a one step ahead of IMRT because multiple biological and anatomical imaging methods are combined into the radiation therapy treatment process. IGRT’s overarching aim is to target tumours much more precisely and sparing normal tissues. The machines in Reliance Hospital Cancer Care - Solapur feature a CT scanner with kilovoltage (kV) imaging facility that can match the planned image with the treatment image accurately online and offline.
IMRT is a specialised type of 3D conformal radiotherapy. Intensity-modulated radiation lets the intensity of each radiation beam to be modulated. Each beam is separated into thousands of beamlets so each field can have one or many areas of high-intensity radiation and any amount of lower intensity areas within the same field. This allows greater control of dose distribution with the target tumour or area.
